Obama set to cut number of US forces in Afghanistan

President Barack Obama will set the course for drawing down the war in Afghanistan tomorrow, when he is expected to announce plans to remove around 10,000 American troops in less than a year.

In a prime-time address from the White House, Mr Obama is likely to outline a phased withdrawal that will send 5,000 troops home this summer and an additional 5,000 by winter or spring 2012, according to a senior US defence official.
